SAD-IRON.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed May 2, 1910. Serial No. 558,995.

To all whom it may concern:

Be it known that I, JOHN W. LIMBERT, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented new and useful Improvements in Sad-Irons, of which thefollowing is a specification.

This invention relates to sad-irons of that class which are heated bythe combustion of a jet of commingled air and gas interiorlyapplied, andone of the objects of the invention is to provide a was-heated sad-ironcomprising the novel features of convenience, durability and generaleffectiveness embodying means for evenly heating the iron throughout theentire area of its smoothing surface.

The invention further contemplates providing a sad-iron of the characternamed having a hollow body portion adapted to contain a fluid fuelburner and having the upper portion of the body closed bya suitablecover containing means to support a mixing chamberand a handlefor themanipulation of the iron, said handle being formed hollow and providedwith a connection to receive the end of a flexible hose or pipe by whichthe fluid fuel is conveyed to the burner. It is also contemplated thatthe connection for the fluid fuel-conducting means will be so positionedon the handle that the conducting means will be held from contact withthe clothes or material on which the smoothing surface of the iron is'em ployed, and by mounting the'mixing chamber, handle and fluid-fuelburner upon the cover, the entire mechanism of the sad-iron is removedat will from the body portion thereof.

With the foregoing and other objects in view, the invention consists inthe novel construction, combination and arrangement of partsconstituting the invention to be hereinafter specifically described andillustrated in the accompanying drawing which forms a part hereofwherein is shown the preferred embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

The drawing presented is a vertical, central, longitudinal, sectionalview of a gasheated sad-iron embodying this invention.

Referring to the drawing, the reference numeral 1 denotes the bodyportion of the iron having a side wall 2 forming a central cavity orrecess 3. The upper portion of this wall 2 is preferably provided withoneor more lateral openings 4: positioned near the rear portion of theiron, for a purpose to be later described.

In practice, I prefer to make the body portion of the iron with twosharpened ends to make the same more readily capable of manipulation.The weight of the iron may be increased or diminished as desired bymaking the walls 2 and bottom of the iron thicker or thinner to increaseor reduce the weight thereof. The recess 3 in the iron is closed bymeans of a cover 5 secured to the upper face of the walls 2 by holdfastdevices 6. The cover 5 is provided with an aperture 7 extendingtherethrough and preferably positioned along the medial longitudinalline thereof and said aperture is provided with an inclined inner face.

Positioned in the aperture 7 is the depending portion of a mixingchamber 8 the exterior of which is suitably fashioned to fit within theaperture 7 and below which is a reduced threaded stem 9 preferablyprovided with exterior threads. The mixing chamber is provided with acentral opening 10, the use of which will be later described. The outerupper portion of the mixing chamber 8 is outwardly-flaring to form ashoulder at its point of union with the threaded stem. This flaringportion is adapted to be seated on the upper face of the cover 5 withthe reduced threaded portion 9 extending into the recess 3. Positionedin the recess 3 is a burner 11, preferably constructed in the form of ahollow cylinder with a plurality of minute openings 12 in the lowerportion thereof. This burner 11 is provided with an upwardly-extendinghollow interiorly threaded integral. tube like boss 13 adapted to bescrewed onto the threaded stem 9 for supporting the burner in spacedrelation with respect to the :[ioor of the recess 3. The upper end ofthe boss 13 is adapted to bear against the under face of the cover 5 sosnugly as to hold the mixing chamber and its connected mechanism firmlybut detachably in position.

The upper portion of the mixing chamber 8 is preferably formed with anintegral upwardlyextending arm 14: provided with a laterally-extendinglug 15. The upper end of the arm 14 is formed with ahorizontallyextending head 16 provided with an inteing a match or otherriorly-threaded opening therein which is in open communication with apassage 17 which extends outwardly into the lug 15. The under face ofthe lug 15 is provided with an opening 18 communicating with the passage17 and mounted in the opening 18 is a valve-casing 19 through whichextends one or more openings 20. Arranged on the lower end of thevalve-casing 19 and proj ecting downwardly between the openings 20 is aneedlepoint-valve .21 formed integrally with the valve-casing 19. Theexterior of the lower end of the valve-casing 19 is threaded to receivea cup-shaped member 22 having in its lower end a minute conical opening23 the walls of which constitute a valve seat for the valve 21 Mountedexteriorly on the valve-casing 19 between the lower face of the lug 15and the cup-shaped member 22 is a coiled resilient element 24 normallyadapted to frictionally-engage the cup-shaped member 22 for preventingunintentional revolution thereof.

Secured in the threaded opening in the head 16 is a horizontal pipe 25having its outer end threaded to receive a nut 26 the position of whichmay be adjusted by rotating the same. Inclosing the pipe 25 is a handle27 of heat-insulating material such as wood having its ends preferablyproperly recessed to receive the projecting end of the head 16 and aportion of the inner end of the nut 26 and which is held in positionthrough the clamping action of the latter. The nut 26 is hollow andprovided with a threaded opening in its outer end to receive a nipple 28to which is connected a flexible fuelsupply-pipe 29 the opposite end ofwhich is connected to some suitable source of fluidfuel-supply.

The operation of the device is as follows: The parts being assembled, ashereinbefore described, and with the cup-shaped member 22 brought to aposition to withdraw the needle-point-valve 21 from its seat in theopening 23, a supply of fluid-fuel such as gas is supplied to the devicethrough the fluid-fuel-supply-pipe 29, from whence it passes through thepipe 25 into the passage 17 and downwardly through the openings 20 intothe cup-shaped member 22 and out wardly therefrom in a fine jet. Thefluidfuel-supply is fed under such pressure as will cause it to beprojected from the minute opening 23 through the opening 10 in thedepending portion of the mixing chamber, in doing which it draws inoxygen from the surrounding atmosphere which is carried with thefluid-fuel into the burner 11, during whichoperation'the gas and oxygenare thoroughly c'ommingled. The c'omming'led gas and air escape throughthe openings 12 and the fluid-fuel properly mixed-with the properproportion of air is ignited by passsuitable igniting ingas both inregard to the time also that different gas-plants supply differentpressures of gas to the consumers and hence in order to obtain completeand perfect combustion the supply of fluid-fuel which is passed throughthe opening 23 may be controlled by shifting the position of thecup-shaped member to enlarge or contract the passage for the gas thereinin order to regulate the supply of fluid-fuel with respect to thepressure thereof.
